The present invention relates to a work station for packing
to be picked on a shipping carrier, in particular
on a pallet or in a roll container, the workplace comprising:
a packing station; a stage, up
the packing station is arranged; a shipping carrier station,
the below the stage
is arranged; a lifting device for lifting an empty or
partially packed shipping carrier
at a height
the packing station, so that the empty or partially packed shipping carrier with
can be packed for picking articles, and for lowering
ready packed shipping carrier,
and a method of packing according to claim 26.
The present invention further relates to a method for packing
to be picked on a shipping carrier.
From the document US 4,088,237 A
entitled "STORAGE AND RETRIEVAL SYSTEM" discloses a method of packaging comprising the steps of: transporting articles to be picked stored on load carriers from a warehouse for load carriers via a conveyor for load carriers to a packing station; Launching the articles to be picked up on the handling equipment for loading equipment for the items stored on loading equipment; and packing the tendered items on a shipping carrier.
Order picking according to the state of
Technology is jobs
for packing articles to be picked, in which
the articles individually

be transported to a packing station. The picking takes place
according to the principle "goods

Rolls, at the lower end of the packing station is provided. Of the
the individual items and packs them in the packing station.
Packing station includes z. B. a framed shaft, the order picker
put the items in the shaft from the top. In the shaft itself is
For example, a vertically movable pallet arranged on
which the articles to be picked can be packed. Once a
Layer of articles is packed on the pallet, the pallet is customary

to be picked items are stored in a warehouse z. B. in so-called
Pass channels isolated
saved. A flow channel is a channel to understand
which is powered by its one end page with articles and
at its opposite
End is emptied. A typical flow channel has driven

are then correspondingly long. Are many different types of articles stored,
the camp gets very big.
The space requirement is very high. The investment costs are appropriate
Problem with this concept is that items that z. B.
due to the nature of their packaging can be easily damaged (so
called "non-conveyable" and "uglies"), not
individually in flow channels
can be stored.
Another problem is the fact that articles that are statistically very frequently represented per order picking (A-article), with single storage in the pass channel many so-called interchangeable games (single games) required. Under an interplay is understood every change of an article between elements, in particular a conveyor technology, the order picking. The delivery of the article from the flow channel to the conveyor system is referred to, for example, as interplay. The transfer of the article from the conveyor to the workplace would be another example of an interplay. From the channels to lie remote items must then be retrieved "batchwise" to achieve the required performance. A "batch" is the aggregation of multiple orders into an ordered set of orders. The batchwise removal of the articles from the channels creates a mix of articles which must be dissolved at or before the workstations. For this purpose, so-called sorters are used.
Effort that must be operated to statistically frequently represented
Storing or outsourcing articles is large, reducing throughput,
the number of articles that actually picks, for example, per hour
and can be packed.
Such articles also require many
is therefore an object of the present invention, a method
and a work station for packing articles to be picked
to provide a higher
Throughput is possible
and less interplay is required. In particular, one is
gentle transport of the article desired to the workplace.

the description of the following figures are for the same
Elements same reference numerals are used.
1 shows a picking system 100 ,
The picking system 100 includes a high-bay warehouse 10 in which articles to be picked are stored on loading equipment, in particular europallets. Each europallet contains a large number of (sorted) articles to be picked, which are preferably arranged in layered pallet layers.
The picking system 100 also has depalletizing stations 12 . 12 ' , Conveyor techniques 14 . 16 . 20 and 28 , Shelf warehouse 18 . 18 ' and 18 '' , an area 26 for jobs 24 and a shipping area 30 on.
The term "conveyor technology" hereinafter means understood devices, such as roller conveyors, belt conveyors, overhead conveyors, etc., with which items directly or in or on loading equipment, such as, pallets, trays, containers, etc., between individual components of the picking 100 can be transported.
The depalletizing stations 12 . 12 ' singulate the items to be picked, which are in the high-bay warehouse 10 stored on europallets. Preferably, the europallets are depalletized in layers. Empty pallets can be transported using the conveyor 16 to the area 26 be transported. Depalletierte articles can by means of the conveyor technology 14 to the shelf warehouses 18 - 18 '' be transported to be stored there. The storage takes place here preferably on trays, the trays are preferably equipped with one pallet position.
By means of the conveyor technology 20 Afterwards, the trays become the area according to picking orders 26 transported, where at workplaces 24 a packing process takes place in which items to be packed are loaded onto a shipping carrier, in particular pallets or roll containers. The area 26 lies at a higher level than the conveyor technology 28 , The conveyor technology 28 serves to transport ready-packed shipping carriers to the area 30 where the shipping carriers are made ready for despatch to be finally delivered, for example by truck.
2 shows a perspective view under a platform on which the area 26 is arranged. In the 2 be by means of conveyor technology 16 Empty shipping carrier, here pallet stack, to a separating station 32 for shipping carrier 34 transported. The separation station 32 separates the pallet stacks. The separation station 32 is optional and can be omitted if the Depalettierungsstationen 12 . 12 ' (see. 1 ) do not form pallet stacks, which they convey via the conveyor technology 16 in the direction of the packing area 26 Send. Alternatively, empty shipping carriers 34 be provided in a different way.
Isolated shipping carrier 34 be by means of another conveyor 36 under the area 26 spent. The conveyor technology 36 is at a lower level 38 , here the hall floor, arranged.
In the presentation of the 3 Looking at the end of the conveyor technology 36 of the 2 ,
The conveyor technology 36 has branch lines 37 on that to lifting devices 40 lead to empty shipping carrier 34 jobs 24 that are in one higher level. The lifting devices 40 are in vertical direction 42 (see double arrow), in particular between a first position and a second position movable. In the first position is the lifting device 40 to the level 38 lowered to empty shipping carrier 34 from the branch lines 37 to take over. For this purpose, the lifting device 40 Preferably, a corresponding load-carrying means, which is suitable for receiving and dispensing shipping carriers. In the second position is the lifting device 40 proceed in such a way that a dispatch carrier in the amount of the workplace 24 is tendered, as will be explained in more detail later.
At the level 38 So are shipping carrier stations 43 arranged, the at least the lifting device 40 include.
Referring to 4 is another perspective view of the 3 shown.
Below the platform on which the workplace 24 is arranged, is a winding device 46 , preferably directly below it, arranged. With the help of the winding device 46 Film webs can be outside around the shipping carrier (not shown here), so that items that were stacked on this shipping carrier can be wrapped with the film when the shipping carrier by means of the lifting device 40 was lowered accordingly. As soon as a layer on the shipping carrier (fully) is packed, the lifting device 40 lowered by the height of this layer. This can be automated or caused by a picker.
In the 4 is next to the shelf warehouses 18 a warehouse 44 presented for individual articles, which in the 1 not shown.
In 5 is a job 24 shown in detail according to the present invention. The workplace 24 for packing articles to be picked is from a packer 48 served.
The packer 48 packs individual items 50 or article of an article layer 52 on a shipping carrier. The article layer 52 consists of a large number of individual articles 50 on a tray 54 , in particular in the form of a pallet position, at the workplace 24 to be provided.
The individual articles 50 be here on a train 56 here lateral guide surfaces 58 has, to the packer 48 directed. The train 56 can in a tray 59 end of which the packer 48 the articles to be picked 50 can take. Filing 59 prevents for one, that the article 50 from the train 56 falling off. On the other hand, the packer wins 48 Time to decide where to find the article 50 placed on the shipping carrier, or to pack items from trays. The train 56 is preferably used for the delivery of slow runners. It may be formed of rollers, of which preferably some are braked.
The term "slow runner" is understood to mean articles that occur statistically less frequently per picking order and are therefore not requested as often as high-speed runners. High-speed (A-article) are preferably on the trays 54 via a conveyor technology 60 for loading equipment to the workplace 24 transported. In conveyor technology 60 this is a roller conveyor made of rollers 62 is formed. But it can also be a different conveyor technology (support chains, belt conveyor, preferably double track, etc.) can be used.
The packer 48 So either takes articles 50 from the filing 59 or article 52 from the shelves 54 (Capacity up to 250 kg) to put them in a packing station 64 preferably a frame 66 has to pack. The frame 66 serves for the lateral stabilization of the packed articles. At least one side of the frame 66 can be foldable or retractable designed to facilitate the packer access to the shipping carrier. It also makes it easier to repair faults and make service easier. Access to the shipping carrier is basically possible from three sides, which represents a further advantage of the present invention, as the packer 48 does not have to stretch too much, but can simply pack from another side.
the items are not directly on a shipping carrier, such. B. a roll container,
can be packed
since the lateral support elements
of the roll container would protrude from the packing station and
would hinder the packing process,
Alternatively, a stacking plate, such as. As a sheet used
become. On this sheet the articles are stacked. If the article pile
is ready, the sheet is placed on a shipping carrier (vertical)
detached and (horizontally) pulled out, similar to a cake server
under one piece
Cake is pulled out.
In the 5 The shipping carrier is not visible because there are already a variety of articles stacked on it. It is understood that the 5 a top view of the platform of 2 respectively. 3 shows. Empty shipping carrier 34 will be from the level below the platform 38 by means of the lifting device 40 (see. 3 and 4 ) on the level of the workplace 24 raised. Once a layer on the shipping carrier is fully packed, the lifting device 40 automated by a layer height or by a Tastenbetäti (key in 5 not shown) by the packer 48 be lowered. If a stacking plate is used, the shipping carrier will be at the level of the level 38 provided and the stacking plate is lowered gradually.
Furthermore, there is the conveyor technology 60 of the 5 from two routes. The one route is used to deliver loading trays 54 whereas the other way to remove the trays 54 serves. The change from one to the other route can also be automated.
It should also be noted that the railway 56 slightly opposite the horizontal, in which the conveyor 60 is arranged, is inclined at an angle α. The train 56 is therefore inclined to keep the articles 50 due to gravity (if necessary) by itself for filing 59 slip. Here, as already mentioned above, roller conveyors can be used, which can be braked and operated clocked.
In addition, the workflow can be reversed. This means that the workstation can also be used to store items in the warehouse. Items to be stored are tendered via the packing station. The packer 48 removes the items and also packs them trays, which in turn are transported to the warehouse. It is understood that the packer could also be replaced by a suitably designed robot.
Reversal of the work flow has the advantage that in times lower
Packing the camp can be refilled, and indeed of such
Packers with packing operations
are not busy.
Return items that are delivered on pallets, dissolved and into the
It is further understood that one or more tracks 56 to the order picker 48 can be performed.
Likewise, several conveyor technology routes can be provided for loading equipment. So z. B. three routes are provided, of which deliver the two outer routes shelves and removed the middle distance empty or partially empty trays. In this case, it is beneficial if two packers 48 work at the packing station at the same time. It goes without saying that several packers could also work at the packing station.
The workplace 24 is characterized among other things by its high ergonomics. The packer 48 almost does not have to move (run) to pack articles. Should it nevertheless emerge that the packer 48 a place where the carrier can not reach well, so the packer 48 around the frame 66 run to get a better position for packing. Preferably, the packer is running 48 However not. The loads coming from the packer 48 be moved, are limited to the weight of the article. The shelves 54 do not have to be from the packer 48 to be moved. The throughput increases enormously. Fast runners are about trays and slow-moving over the track 56 to the workplace 24 transported.
6 shows the workplace of 5 from a distant position.
In the right half of the 6 is also a separation station 68 provided, for example, to the conveyor 20 (see. 1 ) is coupled. The conveyor technology 20 can also with the conveyor 60 be connected so that article layers (pallet layers) 52 and individual items 70 (also on trays) to the workplace 24 can be delivered, via the conveyor 20 , Empty shelves 72 for example, to the Depalettierungsstationen 12 . 12 ' (see. 1 ), and then again with articles in the shelf storage 18 to be stored.
It is understood that several jobs 24 can be arranged side by side according to the present invention (see. 1 ). Almost all processes in the picking system 100 are coordinated and controlled by one or more superordinate warehouse computers.
Alternatively, the trays can be guided past several workstations. The trays can be in the area of the beginning of the track 56 unloaded by a picker (not shown in the figures) by the picker takes items from the tray and this on the track. This procedure has the advantage that not every tray has to be guided to the packing station. Thus, a multi-stop strategy for the loading equipment can be tracked.
